SNESMonitorScaling#

Monitors the largest value in each row of the Jacobian of a SNESSolve()

Synopsis#

#include "petsc/private/snesimpl.h"   
PetscErrorCode SNESMonitorScaling(SNES snes, PetscInt its, PetscReal fgnorm, PetscViewerAndFormat *vf)

Collective

Input Parameters#

  • snes - the SNES context

  • its - iteration number

  • fgnorm - 2-norm of residual

  • vf - viewer and format structure

Notes#

This routine prints the largest value in each row of the Jacobian

This is not called directly by users, rather one calls SNESMonitorSet(), with this function as an argument, to cause the monitor to be used during the SNES solve.
